Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the invention, is not Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work under the premise of the every other embodiment that is obtained, belong to the scope of protection of the invention.

Refering to the concrete application scene for shown in Fig. 1, being the embodiment of the present invention, Fig. 1 includes AP and AP Multiple STA in coverage.AP broadcasts a trigger frame, fingers of the STA after the trigger frame is received Fix time and send multi-upstream access signal, AP broadcasts an acknowledgement frame, for being sent for multi-upstream access signal Successful STA is confirmed.

The preferred embodiment of the present invention is described in detail below.

Refering to shown in Fig. 2, the embodiment of the present invention provides a kind of method of multiple access, its detailed process bag Include：

Step 210：AP broadcasts the first trigger frame to the STA in itself coverage, and the first trigger frame is taken With pre-conditioned, for asking to meet specified time hairs of the pre-conditioned STA after the first trigger frame is received Send multi-upstream access signal.

Here pre-conditioned be：Non-sleep state is transferred to from sleep state, or need the triggering AP to carry out down Row transmission, or need to transmit upstream data, or the cache size of up transmission exceedes setting thresholding, or need Transmission high-priority data, or need to transmit the data of specific transactions and/or access style, or particular channel shape State is available or unavailable.

Specifically, AP can carry request in the first trigger frame is transferred to non-sleep state from sleep state The multi-upstream access of STA, or, the data of the request specific access style of transmission are carried in the first trigger frame The multi-upstream access of STA.

Step 220：AP receives the multi-upstream access signal that at least one STA sends, wherein, multi-upstream access Signal includes a mark sequence.

In the multi-upstream access signal of standard, HE-LTF signals, for providing channel estimation reference.STA Can choose whether to send load signal after HE-LTF signals.AP receives HE-LTF signals, and is based on HE-LTF signals carry out channel estimation.Wherein, HE-LTF signals can be the row or column in P-matrix, Can also be the row or column in other orthogonal matrixes, or other low correlated serieses.

Therefore, mark sequence here can be the LTF or LTF for repeating preset times.

Step 230：AP it is determined that the mark sequence that includes in the multi-upstream access signal for receiving, with AP When the mark sequence included in the resource group distributed for the STA for sending the multi-upstream access signal is identical, it is determined that hair The STA of the multi-upstream access signal is given to meet pre-conditioned.

Specifically, AP determines to include the LTF signals generated by LTF in the multi-upstream access signal for receiving Or the LTF generation LTF signals of preset times are repeated, and included in AP determines the multi-upstream access signal The LTF that LTF signals are used, with AP be send the multi-upstream access signal STA distribute resource group in Comprising LTF it is identical when, it is determined that the STA for sending the multi-upstream access signal meets pre-conditioned.

Wherein, AP determines the LTF that the LTF signals included in the multi-upstream access signal for receiving are used, Can use but be not limited to following methods：

AP carries out channel estimation to receiving the subchannel that the multi-upstream access signal is used, and obtains this and up connects Enter the performance number of signal.

For example, the HE-LTF signals that AP is based on receiving carry out channel to the subchannel for receiving the signal Estimate, obtain channel coefficients h, the coefficient can be a plural number, such as in single reception antenna situation, Can be a vector, such as in many reception antenna situations.AP by h modulus and calculating square value, Or other mathematical operations, the performance number of the signal can be obtained.Wherein, the performance number depend on channel gain and The signal transmission power of sender's (i.e. website).

Further, if AP determines that the performance number, more than pre-determined threshold, determines to include by LTF in the signal The LTF signals of generation.

May determine that whether the HE-LTF that has in correspondence subchannel is used by the performance number.Specifically, When the performance number exceeds setting thresholding, AP determines that the HE-LTF that has in the subchannel is used.

Here pre-determined threshold was surveyed by AP before the multi-upstream access signal of at least one STA transmissions is received The noise power or noise power of amount and the determination of jamming power sum, or, by AP according to default money Noise power or noise power and the determination of jamming power sum that source group is obtained.Further, AP passes through Adjusting the thresholding can control STA's to be successfully accessed rate, false drop rate or loss.Wherein, here reserved Resource group refer to be STA distribution resource group after remaining resource group.Orthogonalities of the AP according to mark sequence Matter, and reserved set of resources analysis multi-upstream access signal, obtain noise power or noise power with interference work( Rate sum.

AP determine in the subchannel have HE-LTF by use after, AP is in default LTF set Each LTF is detected, it is determined that generating the LTF that the LTF signals in the multi-upstream access signal are used.

Additionally, AP determine send the multi-upstream access signal STA meet it is pre-conditioned before, can also really Surely receive the subchannel that the multi-upstream access signal is used, if with AP be send the multi-upstream access signal The subchannel included in the resource group of STA distribution is identical, if identical, it is determined that send the multi-upstream access signal STA meet pre-conditioned.

Before step 210 is performed, in order to realize the multiplexing to resource group, itself is covered model by AP At least two STA packets in enclosing, and record group's mark of each STA after packet, and by each Group's identification notification of STA gives corresponding STA.

For example, AP is by STA1, STA2, STA3, STA4, STA5, STA6, it is divided into Liang Ge groups, Group 1 includes STA1, STA3, STA5, and group 2 includes STA2, STA4, STA6.AP to STA1, STA3, STA5 notify that their group is designated 1, and the small of them is notified to STA2, STA4, STA6 Group is designated 2.

When AP broadcasts the first trigger frame at least one STA in itself coverage, can be first The first group mark is carried in trigger frame, AP receives the multi-upstream access signal that at least one STA sends, this When send multi-upstream access signal to AP by identifying and meet pre-conditioned STA with the first group.

For example, STA1, STA3, STA5 are divided into group 1 by AP in upper example, and notify these three STA Their group is designated 1.Now, if AP sends the first trigger frame, request is transferred to from sleep state Group where non-sleep state and STA is designated the multi-upstream access of 1 STA, if STA1 is met from sleeping Group where dormancy state is transferred to non-sleep state, and STA1 is designated 1, STA1 transmission multi-upstream access signals To AP.Now, only group is designated 1 and meets the condition that non-sleep state is transferred to from sleep state STA can just send the first trigger frame that multi-upstream access signal responds AP to AP.

Additionally, the STA in different groups can use identical resource group, AP is by trigger frame Carrying group identifies, and realizes the multiplexing to resource group, and it is the efficiency that STA distributes resource group to improve AP.

Before step 210 is performed, AP needs to distribute resource group for STA.

Specifically, AP can be the STA distribution resource groups in all coverages, or part STA Distribution resource group.For the STA of each allocated resource group, AP can be its one resource group of distribution, Or multiple resource groups, selection that resource group transmission multi-upstream access signal or root are determined by STA itself Multi-upstream access signal is sent according to the instruction selection resource group of AP.And other do not obtain the resource group of distribution STA is still accessed using competitive way.

AP is that STA distribution resources group can include but is not limited to following several situations：

The first method of salary distribution, AP, when being associated with STA, is that STA distributes at least one resource group.

Here a mark sequence, or a LTF, or one LTF and one can be included in resource group Subchannel.

AP can distribute to mono- mark sequence of the STA when at least one resource group is distributed for STA Numbering, or a numbering of LTF, or a numbering numbered with a sub-channels of LTF, or The resource group # of the resource group of person at least one.

For example, a sub-channels and a LTF can in advance be combined one resource group of composition by AP, each money Source group one resource group # of correspondence.

There are M sub-channels in example 1, per unit channel (such as 20MHz), have N number of LTF, the M sub-channels (from 1 open numbering) and the corresponding resource group of n-th LTF (from 1 open numbering) are compiled Number be k=m+M* (n-1).

There are M sub-channels in example 2, per unit channel (such as 20MHz), have N number of LTF, will M-th subchannel (from 1 open numbering) and n-th HE-LTF sequences (from 1 open numbering) correspondence Resource group # be k=n+N* (m-1).

Second method of salary distribution, AP, when being associated with STA, is STA distribution associations ID.

Association ID (Association ID), i.e. AID.AP and STA is by the AID of the STA according to pre- Imputation method can one by one be mapped to a LTF numbering and sub-channels numbering.

Specifically, agreement associates ID using default first operation rule to distribution between AP and STA Computing is performed, the mark sequence included in the resource group for distributing to STA is obtained.

Further, agreement associates ID using default second operation rule to distribution between AP and STA Computing is performed, the subchannel included in the resource group for distribute to STA is obtained.

Here two operation rules can be taken apart and use, it is also possible to be applied in combination.

Example 3, a default radix is subtracted with an AID, for example, the radix can be 0, then using should Difference rounds downwards the numbering for obtaining value as the LTF of distribution divided by subchannel number.If the numbering of LTF Since 0, then numbering of the result directly as the LTF of distribution will be downwards rounded, if the numbering of LTF is from 1 Start, then will round downwards result plus 1 as distribute LTF numbering.

A default radix is subtracted with an AID, for example, the radix can be 0, is then removed with the difference With subchannel number, and the remainder that will be obtained as distribution subchannel numbering.If the numbering of subchannel from 0 start, then the remainder for obtaining directly as distribution subchannel numbering, if the numbering of subchannel is opened from 1 Begin, then the remainder that will be obtained plus 1 as the numbering of the subchannel of distribution.

Assuming that AP with STA1 when associating, the AID for being STA1 distribution is 5.Assuming that default radix is 0, Subchannel number for 5, LTF numbering since 0, the numbering of subchannel since 0, now, 5/5=1, The numbering for understanding the LTF that AP is STA1 distribution is 1, and remainder is 0, it is known that AP is STA1 distribution The numbering of subchannel is 0.

Example 4, a default radix is subtracted with an AID, for example, the radix can be 0.Use the difference Divided by LTF numbers, numbering of the remainder that will be obtained as the LTF of distribution.If the numbering of LTF is opened from 0 Begin, then the remainder that will be obtained, if the numbering of LTF is since 1, is incited somebody to action as the numbering of the LTF of distribution The remainder for obtaining plus 1 as the numbering of the LTF of distribution.

A default radix is subtracted with an AID, for example, the radix can be 0.With the difference divided by LTF Number round up obtain value as distribution subchannel numbering.If the numbering of subchannel is since 0, Numbering of the result that will round up directly as the subchannel of distribution, if the numbering of subchannel is since 1, The result that rounds up plus 1 as distribution subchannel numbering.

Assuming that AP with STA2 when associating, the AID for being STA2 distribution is 6.Assuming that default radix is 0, LTF numbers for 8, LTF numbering since 1, the numbering of subchannel since 1, now, 6/8=0.75, The result that rounds up is 1, it is known that AP is that the numbering of the subchannel of STA1 distribution is 2, and remainder is 6, can Know that AP is 7 for the numbering of the LTF of STA1 distribution.

Above-mentioned the first and second method of salary distribution are that, in AP and station associate, AP is that STA is explicit (the first method of salary distribution) or implicitly (second method of salary distribution) distribute resource group.

The third method of salary distribution, AP carries at least in AP coverages in the first trigger frame of broadcast Individual STA distinguishes corresponding STA ID, and is the resource group of the corresponding STA distribution of each STA ID.

The 4th kind of method of salary distribution, before AP broadcasts the first trigger frame, broadcasts a management frame or a control At least one STA that frame, management frame or control frame are carried in AP coverages distinguishes corresponding STA ID, And be the resource group of the corresponding STA distribution of each STA ID.

The difference of above-mentioned third and fourth kind of method of salary distribution is that AP is the opportunity that STA distributes resource group It is different.

Here STA ID can be MAC Address or AID or Partial AID or active stations ID (Active STA ID) or interim numbering.Wherein, Partial AID are the part in AID, for example, One first 4 of AID.Active STA ID are the ID that AP is active stations distribution, when active stations are transferred to After resting state, AP will not indicate website with the ID.Additionally, AP can about be scheduled on specific one or It is effective using the ID in multiple time periods.AP can also withdraw the ID from STA, and AP sends this again after withdrawal The website will be no longer represented during ID.Interim numbering can be the numbering of website in the frame or previous frame, for example, exist The station that j-th is indicated as true (having data) in Traffic Indication Map (Traffic indication map, TIM) Point, the instruction is schemed for representing website either with or without response data.

For third and fourth kind of method of salary distribution, can use following but be not limited to following such as table 1, table 2, table 3 set of resources matches somebody with somebody table, and create-rule and resolution rules of each set of resources with table are arranged in advance, and will Resolution rules of each set of resources with table are notified to the website of AP coverages.

Example 5, shown in table 1, can carry set of resources in the first trigger frame or control frame or management frame and match somebody with somebody Table, including STA quantity (optional), the STA ID of N number of STA, and be the money of initial STA distribution Source group #.

Cut-off STA ID

Resource group #

In table 3, can be known according to initial STA ID and cut-off STA ID, be which STA is assigned with Resource group, as from initial STA ID to cut-off STA, corresponding STA is assigned with resource group to ID respectively, The resource group # for being assumed to be initial STA distribution is k, then be money that the STA of initial STA ID+1 is distributed Source group # is k+1, for the resource group # of the STA distribution of cut-off STA ID is s+ cut-off STA ID- Initial STA ID-1.

The 5th kind of method of salary distribution, AP carries distributing bit bit bitmaps in the first trigger frame of broadcast.

The 6th kind of method of salary distribution, before AP broadcasts the first trigger frame, broadcasts a management frame or a control Frame, management frame or control frame carry distributing bit bit bitmaps.

Above-mentioned 5th and the difference of the 6th kind of distribution method be that AP is the opportunity that STA distributes resource group It is different.

The STA ID of the initial STA comprising STA to be allocated in distribution bit bitmaps, and N number of bit, N Individual bit corresponds to N number of different STA respectively, and i-th STA ID of bit corresponding STA is starting The STA ID of STA add i to subtract 1；I-th bit corresponding STA is characterized when i-th bit state is 1 Resource group is assigned, wherein, allocated resource group is：Calculate from the 1st bit to i-th bit Occur 1 total degree in position, it is true according to the corresponding relation between the default total degree for occurring 1 and resource group It is fixed from the 1st corresponding resource group of total degree of bit to i-th appearance 1 in bit.

Corresponding relation between the total degree and resource group of default appearance 1 here can be that will provide in advance Source component is prepared, and resource group is numbered, and the total degree and the numbering of resource group that will appear from 1 set up right Should be related to, for example, occur 1 total degree for 1 corresponding resource group # be 1+t, wherein, t be more than Or the integer equal to 0, it is preset value, arranged in advance with STA by AP.Or, will appear from 1 Total degree as similar " AID ", using example 3 or the algorithm of example 4, will set up each occur 1 it is total The mapping relations one by one of number of times and a LTF numbering and sub-channels numbering.

Example 8, as shown in table 4, initial STA ID correspondences Bit (1), if the state of Bit (1) is 1, table Bright initial STA is assigned resource group, and the corresponding STA of Bit (2) are the corresponding STA of starting STA ID+1, If the state of Bit (2) is 0, show that the corresponding STA of initial STA ID+1 are not previously allocated resource group. If the state of Bit (k) is 1, show that the corresponding STA of initial STA ID+k-1 are assigned resource group, it is false If the corresponding STA of starting STA ID+k-1 are STA 5, STA5 is the 3rd website of appearance 1, therefore The total degree for occurring 1 is 3, if the corresponding relation between the default total degree for occurring 1 and resource group is, The total degree for occurring 1 is equal to resource group #, then the resource group # for understanding STA distribution is 3.

The 7th kind of method of salary distribution, AP carries LTF durations or symbol numbers value in the first trigger frame of broadcast.

The 8th kind of method of salary distribution, before AP broadcasts the first trigger frame, broadcasts a management frame or a control Frame, management frame or control frame carry LTF durations or symbol numbers value.

Above-mentioned 7th and the difference of eight kind of method of salary distribution be, AP be the opportunity of STA distribution resource groups not Together.

STA selects qualified LTF as optional mark according to LTF durations or symbol numbers value Sequence.

Example 9, by protocol conventions or prior Signalling exchange between AP and STA, by LTF durations or LTF Symbol numbers are worth corresponding LTF set, such as one P matrix.When AP broadcast the first trigger frame, Or when LTF durations or LTF symbol numbers values are indicated in management frame or control frame, website is according to LTF Duration or LTF symbol numbers values, determine mark sequence, such as LTF from corresponding LTF arrangement sets Collection is combined into the P matrixes of NxN, is taken according to LTF durations or LTF symbol numbers values specific in the P matrixes Row or column (takes row and still takes row by protocol conventions), used as selected mark sequence.

Above-mentioned AP is that the method for salary distribution of STA distribution resource groups can effectively improve AP for website distributes resource The efficiency of group, has saved signaling consumption.

After step 230, AP broadcast acknowledgements frames, acknowledgement frame meets pre-conditioned STA including all Confirmation configured information.

Wherein, confirm that configured information can carry at least one content in the description below as confirmation form：

1) it is all to meet pre-conditioned STA ID.

By taking STA2 as an example, STA2 determines the resource group # correspondence of the resource group of itself use according to table 8 Bit, if Bit state is 1, show that STA2 multi-upstream access signals send successfully, STA2 is full Foot is pre-conditioned.

Additionally, acknowledgement frame is also carried to meet at least one of pre-conditioned STA STA respectively again The new resource group of distribution.

For example, AP sends the first trigger frame, for asking the up of STA for needing to transmit upstream data to connect Enter, STA1 and STA 2 needs to transmit upstream data, after the trigger frame is received, at the appointed time adopts With identical subchannel, the LTF for differing have sent multi-upstream access signal, for example, employ subchannel Numbering is 1 subchannel, but both of which does not send load.AP successfully parses the two signals, and It is determined that both are required to transmit upstream data, in order to ensure efficiency of transmission and payload reception success, both can not Transmission upstream data is carried out on same sub-channels, therefore AP is carried as STA2 again in acknowledgement frame The resource group of distribution, for example, allowing STA2 to send upstream data in subchannel 3.When AP sends second During trigger frame, the STA for confirming in acknowledgement frame just now is indicated to send upstream data in the second trigger frame, this When, STA1 still sends upstream data using original resource group, and STA 2 is sent using newly assigned resource group Upstream data.Optionally, AP with situation can be respectively STA1 according to channel and STA 2 divides respectively With resource group.

After step 230, if AP determines to meet at least one of pre-conditioned STA STA loads Lotus reception failure, new resource is redistributed based on the STA that the second trigger frame of broadcast is payload reception failure Group.

STA can choose whether to send load, if AP has parsed this when multi-upstream access signal is sent STA still payload reception failures.AP can send the second trigger frame, and be the STA of payload reception failure The new resource group of distribution, for example, the channel of free time, to ensure to be properly received load.

As above example, AP the first trigger frames of transmission, need to transmit the up of the STA of upstream data for request Access, STA1 and STA 2 needs to transmit upstream data, after the trigger frame is received, at the appointed time Identical subchannel is employed, the LTF for differing have sent multi-upstream access signal, but both of which is carried Load, is now possible to the situation that AP receives load failure occur, and now, AP can again send out one and touch Hair frame, i.e. the second trigger frame, and for the STA of payload reception failure redistributes resource group.

Refering to shown in Fig. 3, the embodiment of the invention provides a kind of method of multiple access, detailed process bag Include：

Step 310：First STA receives the first trigger frame of AP broadcast, and the first trigger frame carries default bar Part, up connecing is sent for asking to meet specified times of the pre-conditioned STA after the first trigger frame is received Enter signal.

Step 320：First STA determines itself to meet pre-conditioned, then use the AP to be distributed for itself Resource group send multi-upstream access signal to AP, wherein, multi-upstream access signal comprising one mark sequence.

Specifically, specified times of the STA after the first trigger frame is received sends multi-upstream access signal.

Further, a STA can determine the resource group of use according to first trigger frame, and send The number of multi-upstream access signal.For example, the first trigger frame carry it is pre-conditioned be particular channel state for can With or it is unavailable, now a STA sends that corresponding multiple is up to be connect using pre-assigned multiple resource groups Enter signal, be used to feed back the state of corresponding channel.

Here pre-conditioned is arranged in advance by AP and a STA, pre-conditioned to be：Turn from sleep state Enter non-sleep state, or need the triggering AP to carry out downlink transfer, or need to transmit upstream data, or it is up The cache size of transmission exceedes setting thresholding, or needs to transmit high-priority data, or needs to transmit specific industry Business and/or the data of access style, or particular channel state are available or unavailable.

Before step 310, i.e., before the first trigger frame that a STA receives AP broadcast, first STA receives AP and notifies that the group of group where itself identifies.

After group's mark of group where STA acquisitions, a STA receives the carrying of AP broadcast First trigger frame of group's mark.

First STA determines that group's mark group corresponding with group where itself that the first trigger frame is carried marks It is sensible same, and when meeting pre-conditioned, then AP is used for the resource group itself distributed sends multi-upstream access letter Number to AP.

First STA obtains the resource group that AP is itself distribution, including but not limited in the following manner：

The first acquisition pattern：When being associated with AP, it is that itself is distributed at least to obtain AP to first STA One resource group.

Second acquisition pattern：First STA obtains the association that AP is itself distribution when being associated with AP ID。

Agreement performs computing using default first operation rule to associating ID between first STA and AP, The mark sequence included in the resource group of itself is distributed in acquisition.

Optionally, arrange to be held to associating ID using default second operation rule between a STA and AP The subchannel number included in the resource group of itself is distributed in row computing, acquisition.

The third acquisition pattern：First STA receives the first trigger frame of AP broadcast, is taken in the first trigger frame STA ID with a STA, and be the resource group of STA distribution, a STA is touched according to first Hair frame obtains the resource group for itself distribution.

4th kind of acquisition pattern：Before first STA receives the first trigger frame of AP broadcast, AP is received wide The management frame broadcast or a control frame, management frame or control frame carry the STA ID of a STA, with And be the resource group of STA distribution, a STA is obtained as itself is distributed according to management frame or control frame Resource group.

For the third and the 4th kind of acquisition pattern, a STA need in advance obtain resolution table 1, table 2, table 3 rule, then the set of resources according to the rules to respective type parsed with table, obtain AP be from The resource group that status is matched somebody with somebody.

5th kind of acquisition pattern：First STA receives the first trigger frame of AP broadcast, is taken in the first trigger frame Band distributing bit bit bitmaps,

6th kind of acquisition pattern：Before first STA receives the first trigger frame of AP broadcast, AP is received wide The management frame broadcast or a control frame, management frame or control frame carry distributing bit bit bitmaps；

Wherein, the identity ID of the initial STA of STA to be allocated, and N are included in distribution bit bitmaps Individual bit, N number of bit corresponds to N number of different STA, i-th ID of bit corresponding STA respectively For the identity ID of initial STA adds i to subtract 1；I-th bit is characterized when i-th bit state is 1 The corresponding STA in position is assigned resource group, wherein, allocated resource group is：Calculate from the 1st bit Position occurs 1 total degree in bit to i-th, according to the default total degree for occurring 1 and resource group it Between corresponding relation determine from the 1st corresponding resource of total degree of bit to i-th appearance 1 in bit Group.

Embodiment 1：By battery saving mode --- as a example by poll (PS-Poll) application scenarios.

Refering to shown in Fig. 4, AP broadcasts the first trigger frame, for asking to be transferred to non-sleep shape from sleep state The multi-upstream access of the STA of state, after STA1 is transformed into non-sleep (i.e. active) state from sleep state, STA1 sends to carry using allocated resource group in specified subchannel includes what is generated by HE-LTF The multi-upstream access signal of LTF signals, notifies that AP itself has been enter into non-sleep state.AP can be true in acknowledgement frame Recognize STA1 and be transferred to non-sleep state from sleep state, and indicate a upstream or downstream transmission time.

Specifically, AP is before the first trigger frame is broadcasted, in beacon (Beacon) frame, carry needs AP The quantity 5 and 5 STA ID of STA of the STA of resource group are distributed, and for each STA ID is corresponding The resource group of STA distribution, i.e. set of resources match somebody with somebody table.As shown in table 9：

Table 9

STA quantity	Resource group #	STA1 ID	STA2 ID	…	STA_N ID
						5	1	1	2	…	5

As the table shows, AP, by the beacon frame, is that 5 STA are assigned with resource group, and STA ID are respectively 1st, 2,3,4,5, resource group # 1 is expressed as the money that the STA distribution resource group # that STA ID are 1 is 1 Source group, and deduce for the STA that STA_ID is 2 distributes the resource group ... ... that resource group # is 2, it is STA_ID be 5 STA distribution resource group # be 5 resource group.

Or, before the first trigger frame is broadcasted, AP carries distribution Bit bitmaps to AP in Beacon frames, As shown in table 10：

Table 10

STA quantity (optional)	STA startings ID	Bit(1)	Bit(2)	Bit(3)	Bit(4)	Bit(5)
							5	1	1	0	0	1	1

As shown in Table 10, the state of Bit (1) is 1, represents that the STA distribution resource group # that STA ID are 1 is 1 Resource group；The state of Bit (2) is 0, represents that the STA that STA ID are 2 does not distribute resource group；Similarly, STA ID are that 3 STA does not distribute resource group；The state of Bit (4) is 1, represents that the STA that STA ID are 4 divides With the resource group that resource group # is 2；The state of Bit (5) is 1, represents the STA distribution resources that STA ID are 5 Group # is 3 resource group.

Moreover, it is assumed that each set of resources is with table or distribution Bit bitmap one user's group of correspondence, in set of resources With can also include an object time in table or distribution Bit bitmaps, for indicating the STA in corresponding user's group Waken up in the object time.Meanwhile, can be by different resource group allocation table or the corresponding user's component of distribution Bit bitmaps With identical resource group, the different object times are carried, to realize the multiplexing to resource group, and avoid resource Group is used to be obscured.Meanwhile, STA only wakes up in the object time for indicating, and can avoid receiving other STA transmission Multi-upstream access signal, maximize power save.

In addition, may further indicate that mark sequence occupies the symbol numbers of OFDMA, and load in the first trigger frame Maximum length in time.

AP can in acknowledgement frame the STA ID comprising each STA being successfully accessed, i.e. confirmation form, such as table 11 It is shown.

Table 11

STA quantity	STA1 ID	STA2 ID	STA3 ID	STA_4 ID
					4	1	3	5	6

As table 11 understands, STA ID are 1,3,5,6 website, multi-upstream access success.

Or, AP carries confirmation Bit bitmaps in acknowledgement frame, as shown in table 12.

Table 12

STA quantity	Initial STA ID	Bit(1)	Bit(2)	Bit(3)	Bit(4)	Bit(5)	Bit(6)
								4	1	1	0	1	0	1	1

As table 12 understands, Bit states are 1 corresponding website, and multi-upstream access success then understands STA ID It is 1,3,5,6 website, multi-upstream access is successful,
